I am 52. no period since jan and am swollen. i was given progesterone to bring it on but concerned about negative i read about hormone replacement?

Progesterone trial: If you were given a short 10 day trial of progesterone to "initiate a period" then there are very few long term effects from that hormonal medication. This does not constitute HRT.(hormone replacement therapy). The MD is simply trying to determine if you are beginning the menopausal process.

Progesterone: Progesterone is given to prepare the lining of the uterus for shedding. At 52, you are probably still producing some estrogen, but not ovulating. There is minimal concern about progesterone at this point, and you might want to continue to take replacement estrogen with periodic progesterone orally to ward off PMS, etc..
